Across
  1. 3. Branches that extend from the cell body of the neuron, function to receive neurotransmitters (via facilitated diffusion) from the synapse
  2. 4. nervous system brain and spinal cord
  3. 5. Gap between neurons (between dendrites and terminal buds)
  4. 8. terminal Portion of the neuron which releases neurotransmitters into the synapse (sends message to next neuron)
  5. 9. nervous system Subdivision of the peripheral nervous system that regulates involuntary functions (things our body does without having to think about doing it) Example - heart beat, blood pressure, blinking, etc.
Down
  1. 1. sheath Insulation around the axon of the neuron, contains electrical impulse within the neuron.
  2. 2. nervous system the nervous system outside the brain and spinal cord
  3. 4. body Many organelles such as the nucleus are found here
  4. 5. nervous system The division of the peripheral nervous system that controls the body's skeletal muscles (voluntary movements and actions)
  5. 6. Transmits electrical impulse down the body of the neuron, insulated by the myelin sheath
  6. 7. Specialized cell found in the nervous system, functions to transmit nerve impulses
